Title: Positioner for sampler of rotor for centrifugal separator
Inventor: SATOU YASUTAKE
IPC: B04B5/02
Filed: 1979-08-21
Abstract: PURPOSE: To perform the charging or discharging of sample effectively without resorting to manual operation by automatizing a matching operation for a sample- housing backet with the opening of the upper plate of a rotor chamber.  
     CONSTITUTION: When the rotation of a rotor is stopped as a set time passes, an air cylinder 22 operates to lift a bar 17, and the low-speed rotation force of an index motor 16 is transmitted to the output shaft 10 of a main motor 9 and further to the rotor. When the output shaft 10 of the main motor 9 rotates at low speed and at the same time the index disc 11 fitted to the output shaft 10 is turned, the optical element 12 detects a slit provided in the periphery of the disc 11 and makes the sample-housing backet 3 fitted to the rotor coincide with a given position, or the opening 8 of the upper plate of a rotor chamber 2 and stops it. Then, the charging or discharging operation of a test tube-housing rack 25 can be automatically performed by a sample charger provided at the upper part of the opening 8.

Title: Electromagnetic hydraulic actuator control device
Inventor: AKAGI MOTONAGA
IPC: F15B9/09
Filed: 1984-05-25
Abstract: PURPOSE:To prevent creation of hunting, by feeding an electric signal of a duty ratio varying with slippage from a target position of a piston rod to a pair of solenoids of an electromagnetic hydraulic actuator. CONSTITUTION:In this actuator, a first solenoid 26 acts to drive a piston rod 20 in the extending direction, while a second solenoid 27 acts to drive the piston rod 20 in the contracting direction. Until the piston rod 20 reaches a predetermined contracted position, a drive unit 70 receives a signal from a stroke sensor 21 and supplies a signal of a duty ration 50% to the first solenoid. As the rod further approaches to the target position, the duty ratio of the signal is decreased up to 0% at the target position. Since the second solenoid is also driven in the same manner, the rod is automatically braked in the vicinity of the target position to thereby prevent creation of hunting.

Title: Tent curtain stretcher
Inventor: NAMIKI MICHIHARU
IPC: E04H15/00
Filed: 1993-04-12
Abstract: PURPOSE:To tense a tent curtain simply and uniformly by stretching the lower edge section of the tent curtain on columnar materials installed among a plurality of post- shaped roof bearing-material lower ends, pulling up the lower edge sections of the tent curtain through a screw lifting and lowering mechanism mounted on a bearing material section and stretching the curtain. CONSTITUTION:A screw shaft 61 is elevated by rotating a driving nut 63, and a circular material 40 is pushed up and fixed by a temporary fixing bolt 31. The lower edge section of a tent curtain 10 is stretched on the lower side of the circular material 40, and a slender material 50 is caught to a slender material catch 70. When the bolt 31 is loosened, the bolt 31 is clamped to a columnar bearing material 45 under the state and the position of the circular material 40 is fixed because the circular material 40 is lowered and the curtain 10 is to some extent tensed. The nut 63 is turned, a screw 61 is revolved and brought down while being abutted against the circular material 40 and the circular material 40 is lowered, and the curtain 10 is pushed and tensed by the circular material 40. When a tent is stretched and the curtain 10 is loosened after a long time passes, the screw 61 is rotated, and the curtain is tensed again. Accordingly, the tent curtain can be stretched simply and uniformly, and can be tightened easily and can be tensed even when the curtain is loosened.

Title: Light source apparatus for measurement
Inventor: WAKANA SHINICHI
IPC: G01H9/00
Filed: 1986-05-10
Abstract: PURPOSE:To make it possible to correct the dispersion of oscillation frequency difference between two semiconductor laser elements, by a method wherein two semiconductor elements arranged on a heat sink with temperature gradient are used as a laser light source, and the temperature gradient is produced also between the two elements. CONSTITUTION:Semiconductor laser elements 1 and 2 having different oscillation frequencies are used, whose injection current can be controlled by a current controlling part 3. Further, the elements 1 and 2 are arranged along a temperature gradient on a heat sink 4 on which the temperature gradient is produced. This temperature gradient is produced from both ends of the heat sink 4 as the result of a specific temperature control applying a temperature controlling part 5. As the temperature gradient of the heat sink 4 can be controlled by the temperature controlling part 5, the temperature gradient can be produced also between the two semiconductor laser elements 1 and 2. Thereby, a desired frequency difference ¦f1-f2¦ can be obtained in response to the temperature gradient rather simply and exactly.

Title: Percussive sound judging device
Inventor: IKEDA MASAHIRO
IPC: G01N29/12
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To improve the reliability of judgment from percussive sounds at the time of judging the content of a can, etc. SOLUTION: While a can 1 is percussed with a hammer, the exciting force of the hammer is detected by means of a vibration detector 11 and the percussive sounds are detected by means of a microphone 3. The detected sounds are divided into a time-sequential signals in a plurality of frequency bands by means of analog BPFs 41 and the maximum values of the signals are stored in peak hold circuits 43. In a reference value setting mode, reference peak values and reference values are respectively stored in reference value setters 16 and 46. In a judgment mode, a ratio computing element 15 computes the ratios between the exciting force and the peak reference values and correctors 44 respectively correct the detected maximum values by using the ratios.  Comparators 45 compare the corrected maximum values with the reference values stored in the setter 46 and, when the compared results do not meet a prescribed relation, output judgment signals to an alarm 18. Since the maximum values in the frequency bands are extracted for comparison from the time-sequential signals at every frequency band, the reliability of judgment is improved.
